DNA testing has identified the 1,641st victim of the 9/11 terror attack on the World Trade Center, according to Melissa Quinn at the Washington Examiner. The identity is being withheld out of respect for the family’s request for privacy.

On September 11, 2001, 2,753 were killed when terrorists flew airplanes into the Twin Towers and, 16 years later, there are still 1,112 who remain unidentified.

March 2015 was the last time a victim was identified. As new DNA testing methods are discovered, remains are tested again and again in hopes of bringing closure to families.

The Guardian further explained that the procedure included more sensitive DNA technology used by the medical examiner’s office, with some bone fragments tested over and over, sometimes almost a dozen times, hoping to produce an answer to the identity. Their methods and tenacity are encouraging, as explained in this expanded description of poring over the remains.

The sixteenth anniversary of the tragic 9/11 attacks is in four weeks, a time when the nation pauses to remember the loss of 3,000 innocent lives on American soil. Never forget.
